Abstract
Silicon carbide (SiC) whiskers were synthesized from SiO2-CH4-Na(3)AIF(6) s ystem. The whiskers obtained were cylindrical in shape, and they had unifor m diameter (0.1-5.0 mu m) and length (50 mu m-10 mm). They were found to ha ve grown by a Vapor-Liquid-Solid (VLS) mechanism since a catalyst droplet w as observed on the tip of most of the whiskers. The composition of the AI-S i droplets was determined by means of EDAX. As no researchers have previous ly reported on AI-SI droplets, we conducted a detailed analysis of them in this study.
